This is what is meant by versioning

No Versioning, no backup.

Quote from Adoby

rsync is very well tested...

And your Script?

And your c++ Programm?

You can use rsnapshot without the Plugin.

Use Something tested...

To keep more days/weeks/years of Backup with little extra space usage, use rsnapshot

Quote from mervincm

Did I miss anything big, or are those the issues you were speaking to?

Nothing Special about OMV. It is an General advice. I would avoid the complexity.

BTRFS Supports RAID. So you do Not News the added complexity of mdadm.

Having said that, there are scenarios, in which a RAID5 in btrfs can be unstable (unclean shutdown PLUS a failed Drive)

Quote from eptesicus

. I'm taking on more risk going with RAID50 in lieu of RAID60, and I'm fine with that.

But why not Just a RAID6 without the 0.

What ist the benefit of 50 vs 6, that you are after?

Your Post ist very hard to read.

And: Don't Tell us all the Details, but only what could bei relevant.

Anyway:

Do Not Mix mdadm RAID with btrfs

Use the btrfs RAID Levels instead.

Inform yourself about the latest Status of btrfs and RAID 5 though.

Quote from eptesicus

With my RAID50 setup, I have 3x RAID5 arrays striped, so I can lose 3 disks at a time, permitting 1 disk per RAID5

And once you lose two in one Raid5 all Data ist lost.

Why ist this better than raid6?

Hello,

Does it really make Sense to continue this mega Thread?

Solutions get lost in it.

If everyone opens one Thread per topic with a good descriptive Titel, it May lead to questions being answered only once rather than multiple Times.

So, why Not Close this one?

Macom ist right.

RAID is No Backup.

An accidentally deleted File is gone on both Drives.

Just to avoid Others to follows this advice:

Most likely the Kernel was not the fix.

Maybe the reboot or something Else was.

The advice to Upgrade the Kernel was most likely nonsense

Too little information.

And:

Did you try Google?

What If you enter http://195.50.176.200 in your Phone?

No

Hello,

I upgraded to 5.0 recently.

After the upgrade everything works fine, but I was missing the Unionfs page.

Now, in omv-extras, I find two plugins:

-mergerfsfolders

-unionfilesystems

Unfortunately, I am not sure, which one I used before - I think it was unionfilesystems.

After installing both (expecting to find in one of the two to find my drives), I get

OMV\AssertException: The property 'self-mntentref' does not exist in the model 'conf.service.unionfilesystems.filesystem'. in /usr/share/php/openmediavault/config/configobject.inc:71

At each logon.

I found this thread, but it is similar only...

There, the suggestion is to remove the <mlimit>..

But I do not think that this makes sense here, as I think that the self-mntentref is needed.

        <options>defaults,allow_other,direct_io,use_ino</options>
      </filesystem>
    </unionfilesystems>

I still get the same error.

Which of the two plugins should I use, and how can I fix this issue?

Zeig doch Mal dein Log nach dem awk kommando

Hello,

I understand. Thank you.

I recommend running

borg list /path/to/repo

This will return a list of backups

Or better

borg info /path/to/repo   

If a passphrase is needed, it will ask:

Enter passphrase for key /path/to/repo

And then answer

Repository ID: 4c6016518ca680c2b5e0aca1ef7090b4e15f272adb6a437756063ac89fbede59
Location: /path/to/repo
Encrypted: Yes (repokey)

Unique chunks         Total chunks
Chunk index:                  669001             22373540

If you add --json to the command, you will get a more suitable output.

Hello,

I can only tell you the obvious and you should consider that the obvious is the answer.

And as you do not say why my answer is wrong/not applicable in your view, I cannot help further.

You write

Quote

don't know how to get borg to use an existing folder when trying to make a new repo

And this is the problem: you should not create a new repo. You should just skip the step of creating a new one in case the user already has a repo. In that case, Borg will just use that.

Quote from ryecoaaron

I could easily add what I think is right

You could state that and then you would get feedback.

But you just ask not to state the obvious. How shall we do that, if we don't know what you deem obvious and also not, what you think is wrong with the obvious.

Greetings,

Hendrik
